Postscript: The Time is Growing Short

POSTCRIPT
I published the blog post below in 2017. It discusses a scientific analysis and climate-change warning published in the journal Nature.
The critical element of the scientists’ conclusion was the absolutely necessity to begin immediately reducing CO2 emissions. Progress was pinned to six milestones that had to be reached by 2020. Here we are in 2020. Unfortunately, global CO2 emissions increased in 2018 and 2019 and none of the six milestones was reached. Likewise, the other disasters I mentioned are continuing to accelerate. The likelihood that human civilization will continue to progress and flourish in years to come is perhaps exactly equal to the number of times “biodiversity” or “global wildlife extinction” has been mentioned in the Democratic presidential debates: Zero. But who knows? Perhaps this year’s weather will provoke a massive mobilization similar to what it took to combat the Nazis.

The 2017 Blog Post

GR [in 2017]:  An article from June, 2016 should be on everyone’s mind now. Here’s my discussion followed by a link to the article.

A group of scientists analyzed the sources of CO2 and the dynamic relationship between the quantity of CO2 in the atmosphere and global temperature to devise a global carbon budget they could use to assess the effect of timing of changes in CO2 emissions. The analysis enabled them to calculate the changes we must make to preserve a livable climate. You’ll have to read the article to see the individual sources of CO2 that must be adjusted. I wanted to mention the timing for the budget. The analysis shows that if CO2 emissions begin to fall immediately and reach zero in 30 years, we will remain within the global warming limits set by the Paris treaty. After the flat emissions of 2014, 2015, and 2016, the authors believed that the fall in emissions was ready to begin. This is good, because their budget shows that if we wait to 2020 to start tapering off CO2 production, we only get 20 years to reach zero emissions. If we wait to 2025, we get less than 10 years to reach zero. Transforming our energy use that quickly would be impossible.

SO, how are we doing. Six months after the analysis was published, we find that 2017 emissions have gone up, not down. Lot’s of positive changes have begun, but we have to wait to see what happens in 2018. If we begin to taper off CO2 emissions by 2020, we will have 20 years to reach zero emissions. I suggest you take a look at the six milestones the authors believe must be reached by 2020. Then you can monitor the world’s progress toward painful climate change (the Paris treaty) or disastrous climate change (with too many storms, fires, heat waves, and rising seas).

Climate change is just one of the approaching disasters. Human population and its impact is growing, wildlife species are going extinct at incredible rates, freshwater supplies are dropping, and toxic wastes are building up. If we can’t do much more than take our CO2 emissions to zero over the next 20 years, most of the diversity and beauty of life on Earth will disappear.

Biodiversity Loss and Human Extinction

Global Extinction Emergency

Present day human impacts are causing global extinctions comparable in number to the dinosaur extinction of 65 million years ago. Research reports across all plant and animal groups are documenting falling numbers, and the losses are speeding up.

The loss of species and ecosystems is at least as dangerous as climate change. People cause both as we use and harvest soils, plants, animals, and fossil fuels. Soon we will begin to reach the limits of nature’s reserves. As marine fisheries and farming regions lose their productivity, there will be moments when the failure of one region to meet the needs of people will cause demands to shift to other regions. Then, like falling dominos, the cascading failure of ecosystems will force the same desperate international migrations that have already begun due to climate change. The great danger is that once it begins, the cascade of extinction and ecosystem failure will ripple around the world and will be unstoppable.

Here’s a story about the status of international efforts to halt biodiversity loss. As you can see, the extinction emergency is not being treated as an emergency. We need another Greta Thunberg to arise and lead the protest against extinction. And we need it now.

Saving Nature and Human Civilization

Government Inaction on the Climate Emergency

More than 90% of the countries signing the Paris Climate Agreement have failed to meet their target emission reductions. Some countries, notably the U. S., have instead grown their emissions beyond the worst-case predictions.

BLUNDELL

The original goal was to keep global temperature rise below 1.5 degrees celsius (2.7 degrees fahrenheit). However, national actions that would keep warming below 2 degrees celsius (3.6 degrees fahrenheit) were acceptable. Only three countries are on track to do either of these. Most are on the way to increases of 3 or 4 degrees celsius. Scientist fear that these higher increases will wipe out human civilization.

Government Inaction on the Mass Extinction of Wildlife

At the same time global warming is threatening humanity, global wildlife numbers are plummeting. This itself threatens the survival of human civilization even without the compounding effect of global warming. Under threat here is the soil, the foundation of life on Earth. And in the oceans, the delicate chemical and temperature balance that allows abundant marine life to exist.

The Extinction Rebellion

As the majority of the world’s citizens become aware that both climate and extinction are in danger of spiraling out of control, there are growing efforts to direct our governments to take action. Since the time India separated from the British Empire, we have all known that peaceful demonstration and protest can force major changes. The Student Strike, the progressive politics embodied by the Green New Deal, and The Sunrise Movement are starting to have an impact on government policies. It is essential that these groups welcome and endorse the efforts of the Extinction Rebellion. It is essential that all of us take part in local demonstrations sponsored by these and other groups concerned with avoiding extinction.

Here are the basic demands of the Extinction Rebellion. I expect these will be expanded in the months ahead:

WE DEMAND:

These demands only represent XR US. They are still in the process of development.

  1. That the Government must tell the truth about the climate and wider ecological emergency, it must reverse all policies not in alignment with that position and must work alongside the media to communicate the urgency for change including what individuals, communities and businesses need to do.
  2. The Government must enact legally-binding policies to reduce carbon emissions to net zero by 2025 and take further action to remove the excess of atmospheric greenhouse gases. It must cooperate internationally so that the global economy runs on no more than half a planet’s worth of resources per year.

  3. We do not trust our Government to make the bold, swift and long-term changes necessary to achieve these changes and we do not intend to hand further power to our politicians. Instead we demand a Citizens’ Assembly to oversee the changes, as we rise from the wreckage, creating a democracy fit for purpose.

  4. We demand a just transition that prioritizes the most vulnerable people and indigenous sovereignty; establishes reparations and remediation led by and for Black people, Indigenous people, people of color and poor communities for years of environmental injustice, establishes legal rights for ecosystems to thrive and regenerate in perpetuity, and repairs the effects of ongoing ecocide to prevent extinction of human and all species, in order to maintain a livable, just planet for all.

The first U. S. XR (Extinction Rebellion) events begin tomorrow.

Habitat loss threatens all our futures, world leaders warned

GR: I suppose that we all know what’s causing habitat loss. The human population has grown without limits and like bacteria in a petri dish, we are using up the Earth’s resources. The outcome was predicted long ago. Couple those predictions with the unexpected rapid intensification of climate change and you can see why our ultra rich citizens are hoping to find water on Mars and other planets. They hope to soon be saying, “So long and thanks for all the fish.” Of course, the rest of us can’t wait for the day that they all fly away in an Elon Musk version of the Golgafrinchan Ark Fleet Ship B.

“As a UN conference convenes to work out a new deal for protecting the planet’s biodiversity, the focus falls on the nations that are not attending.

“Amid the worst loss of life on Earth since the demise of the dinosaurs, the agenda at the Convention on Biological Diversity (CBD) in the Egyptian resort of Sharm el-Sheikh could hardly be more important, but the spirit of international collaboration appears to be as much at risk of extinction as the world’s endangered wildlife. The United States has never signed up and Brazil is among a growing group of countries where new nationalist leaders are shifting away from global cooperation.

“The two-week meeting of the CBD is its first in two years. It has always been the neglected sibling of its twin, the United Nations Framework Convention on Climate Change. The two organisations were conceived amid great hope at the Rio Earth summit in 1992 but while the energy transition has attracted heads of state interested in billion-dollar renewable projects, the effort to save the natural world has been left to weak environment ministries, conservation NGOs and underfunded scientists” –Jonathan Watts. Habitat loss threatens all our futures, world leaders warned | World news | The Guardian
